acids and alkalis Flashcards
what does a soluble non metal oxide dissolve to produce
acid
what does a soluble metal oxide dissolve to produce
alkali (alkali metals)
what ph does acids have
below 7
what ph does alkali’s have
above 7
what ph does a neutral solution have
7
what ion does an acid always have
H+ / hydrogen ions
what ion does an alkali always have
OH- / hydroxide ions
what is the ph scale a measure of
the power/concentration of hydrogen ions
an acidic solution has a higher concentration of what
H+ ions than OH- ions
an alkaline solution has a higher concentration of what
OH- ions than H+ ions
water and neutral solutions have an equal amount of what
H+ ions and OH- ions
what happens to the ph in acids when you dilute it
the ph increases to pH 7
what happens to the ph in alkaline when you dilute it
the ph decreases to pH 7
what is a neutralization reaction
its when a solution cancels out the effect of an acid
what is the neutralization reaction solution called
a neutralizer
